The invention, ingeneral," relates toimeans for improving-the sanitaryconditions and efiiciency of water coolers; More particularly, -the invention relatesto' olla. covers for promoting greater circulation of air. around the 1 olla, for preventing deleteriousiaction of'mould ortotherbacteria provide an olla cover which is inexpensively manufactured and which lends itself to attractive design!" motifs as well i as attractive displayto avoid theunsightly appearance of the olla:

Other ob'jectsofthe invention, together with some of theadvantageous features thereof, will appear from the-following description of a "pre ferred embodiment ofthe invention. While I have illustrated the preferred embodiment of my invention in the accompanying drawings, it is to be understood that I am not to be limited to the embodiment shown, as my invention, as defined by the appended claims, can be embodied in a plurality and variety of forms.

Referring to the drawings:

Figure 1 is a medial vertical sectional view of an embodiment of my invention, taken through a portion of a water cooler with the olla cover assembled in position.

Figure 2 is a side elevation of a water cooler including the olla and with the present embodiment of my invention installed thereon.

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Figure 4 is an elevation of an embodiment of the invention illustrating the flexible character of the same which enables the nesting of a plurality of the covers together for ready and inexpensive handling.

Figure 5 is a view taken on the line 5--5 of Figure 4 and illustrating the manner of diminishing the overall dimensions of the cover to permit the nesting together of a plurality thereof.

Figure 6 is a development of the body portion of the embodiment of my invention illustrated in.

Figures 1 to 4 inclusive.

Figure 7 is a development of'the neck and shoulder portion of the embodiment of themvention shown in Figures 1 to4 inclusive.

In its preferred form, the collapsible olla cover of my invention preferablycomprises a generallycylindricallbody portion and-'a' generally coneshaped neck and shoulder portion; both of said portions preferably being formedof flexible'sheet material, such as cardboard, and b eing provided with a series of perforations to permit circulation of 'air about the olla upon which the cover seats in spaced relationship; together with means for detachably fastening the two portions together; and'means at'the extremitiesof each of saidpor tions for detachably interlocking the sameto-;

lateral'extremity, with "a tab l6 havingf li-psf lfllformed tliereon -forinsertion in aperturesf l8 formed in-the-sh'eet' at=the otherlateral extremity thereof. The sheet ll comprises the body portion of my improved olla cover and preferably is scored o-r weakened at spaced intervals, as at l9, so that upon folding the sheet upon itself and interlocking the extremities thereof at the tab l6, lips l1 and apertures 18, a plurality of panels 2| are provided. The sheet II can thus be assembled and detachably fastened at its lateral extremities about the conventional porous jar or olla 22 of the standard water cooler which includes an inverted water bottle 23, the neck 24 of which is disposed in the mouth 26 of the olla, all as illustrated in Figure 1 of the drawings.

In addition to the sheet II, the olla cover of my invention includes a neck and shoulder portion which preferably consists of a sheet 21 also formed of flexible material, such as cardboard, and which preferably is formed into atruncated pyramid, see Figure 2 of the drawings, having a relatively large opening at the center thereof which registers with the mouth 26 of the olla and through which the neck 24 of the bottle 23 protrudes. The sheet 21 conveniently is provided with a series of perforations 28 at spaced intervals circumferentially about the sheet and also is provided with means, such as the tabs 29 and apertures 3! at opposed longitudinal extremities '45 r ible olla cover of my invention can readily be "thereof, to permit detachable'interlocking enportions together.
